Issue Log:
Error: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "From 11.5 days post coitus to postnatal day 5", in ["TREATMENT"]["TREATMENT_DOSEDURATION"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['h', 'weeks', 'days']. Ignore this when more complicated descriptions are required.
Error: The value, "See protocol/methods file", in ["MS"]["ION_SOURCE_TEMPERATURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: The value, "See protocol/methods file", in ["MS"]["ION_SPRAY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "0.4mL/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required.
Error: The value, "5 L", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "600 L", in ["CHROMATOGRAPHY"]["WEAK_WASH_VOLUME"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "600 L", in ["CHROMATOGRAPHY"]["STRONG_WASH_VOLUME"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Error: The value, "17 L", in ["CHROMATOGRAPHY"]["SAMPLE_LOOP_SIZE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_index_type". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The standard column, "other_id", was found in the METABOLITES table as "other_id". If this column contains database IDs for standard databases such as KEGG, PubChem, HMDB, etc., it is recommended to make individual columns for these and not lump them together into a less descriptive "other_id" column.
Warning: The "T52-6" column at position 9 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V32-6" column at position 10 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V38-9" column at position 11 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V44-2" column at position 12 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V47-6" column at position 13 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V69-3" column at position 14 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V77-5" column at position 15 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "V78-6" column at position 16 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
Warning: The "moverz_quant" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri" column at position 3 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "ri_type" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "inchi_key" column at position 6 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
Warning: The "kegg_id" column at position 7 in the ["MS_METABOLITE_DATA"]["Metabolites"] table has all null values.
